CATRA - test results

hello nozh2002, welcome to the forums!

I believe Spyderco does CATRA testing, and for a small fee ($25 or something like that) you can send in a knife and they will run it through their machine. BUCK does CATRA tests as well, IIRC. Try e-mailing those manufacturers, or post on their forums here in the makers and manufacturers section and ask them if they will send you any data.
 
I'm so happy!!!!

Actual, scientific, repeatable, objective, quantitative testing for knives!!!!! I've been searching for this for years!

And look: there's even an ISO standard, ISO 8442-5.2003, for testing knife edge sharpness. Goodby "shaving sharp,"... So long, "hair-popping sharp," good ridance, "scarry sharp." We've got numbers!

And there's one of these CATRA machines right here in Portland, Oregon at Leatherman. It's also interesting to notice that World Kitchen, Cutco, and Master Cutlery have also invested in these.

And they have a corrosion-resistance test machine too. Wouldn't it be nice to run all of the various potions and lotions and snake oils that are sold as rust-protectants through that in a controlled, standardized way and get some real data for a change?

They even have a machine to test the durability of folding knives. It looks a Spyderco under test in the picture.
 
Chuck> spyderco has a number of toys... unless my brain is off from not watching the dealer vid in the last month, they have: catra, q-fog(corrosion tester), breaking machine, goniometre(killed spelling) for angles, torque machine for opening and closing resistance... and I probably missed one.

small fee they'll test a knife for yah, but you can't use the info for commercial use, just knowledge.

Yes, I saw Spyderco and Buck in the list of CATRA customers. The point is to know this information before you bought a knife, not after.
Data sheet I found on http://www.cqbproducts.com/cpm.htm at least gives some idea that CPM S30 V is better then CM 154 which better then 440C in this test.
Also I rmember little chart on the paper I got with my KaBar 1217 comparing 1095 Sandvic 12C27 and D2. So D2 better then Sandvic and better 1095 according to thet chart. But I like to see this on the web as I can see steel composition table.
Thanks, Vassili.
 
CATRA testing is expensive, so most knife companies keep it to themselves, so that their competition dose not benefit from it. Hopefully this will change as steel companies include CATRA testing in their data sheets.

C. J. Buck and Sal Glesser have posted some CATRA data on the forums you can find it by searching “CATRA”.

There is a chemical engineer over on another forum doing tests on various products in a humidity chamber. The first two rounds of tests have been completed. People sent samples of additional products they wanted tested so testing is on going.

Here’s a link to a recent BF thread where this was discussed -

and here are the links to the tests -
